### 问题描述 / What happened

用ai查了一下说是这不是普通意义上的"内容被敏感词拦截"，而是 LiteLLM Proxy 内置的 Moderation/Guardrails 功能在起作用

### 环境 / Environment

- Cindy 版本或 commit / version or commit:
- 平台与版本 / platform & OS version:
- 安装方式 / install method:

### 复现步骤 / Steps to reproduce

对话突然报错，之后怎么继续都是这个报错

### 日志与截图 / Logs & screenshots

_No response_

Start by reproducing the conversation error with the Cindy version, platform, installation method, and complete logs requested in the issue. Then inspect the LiteLLM Proxy moderation or guardrails behavior and the inference gateway at 127.0.0.1:50643; done means identifying whether the failure is in Cindy or the gateway and documenting a confirmed resolution.
